  2. 11. Ecological and evolutionary assembly processes and metacommunity structure

    Author : Mikael Pontarp; Evolutionär ekologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Community; metacommunity; phylogenetic signal; ecology; evolution; assembly process; marine bacteria; habitat filtering; competition; mathematical modeling; simulation; eco-evolutionary;

    Abstract : This thesis aims to elucidate the link between abiotic and biotic effects and biogeographical contingencies, eco-evolutionary assembly processes, and community structure in a spatially explicit metacommunity framework. To this end, we used structure analysis of naturally sampled and experimentally manipulated marine bacterial communities and mathematical eco-evolutionary modeling and simulations of metacommunity assembly.

  4. 12. Bank-Industry Networks and Economic Evolution : An Institutional-Evolutionary Approach

    Author : Thomas Marmefelt; Jönköping University; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Schumpeterian bank-entrepreneur interaction; Bank-industry networks; Innovation; Economic evolution; Endogenous growth; Entropy; Financial institutions; Governance; Conventions; Institutional change; Network commitment; Spontaneous order; Collective action; Evolutionary game theory; Economic history;

    Abstract : The links between institutions and economic evolution, especially between financial institutions and industrial innovation, are poorly understood. Having Schumpeter´s theory of economic evolution as starting point, this study gives an outline of an institutional-evolutionary theory of institutional change, innovation, and financial systems, based on learning-by-financing within bank-industry networks.

  5. 13. Rates and patterns of molecular evolution in avian genomes

    Author : Paulina Bolívar; Hans Ellegren; Carina F. Mugal; Mikkel Heide Schierup; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Molecular evolution; recombination; GC-biased gene conversion; Hill-Robertson interference; effective population size; dN dS; distribution of fitness effects; avian genomes; collared flycatcher; sex chromosomes; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Evolution is the change in inherited characteristics of a population through subsequent generations. The interplay of several evolutionary mechanisms determines the rate at which this change occurs. READ MORE

  6. 14. Rates and patterns of genome evolution in Lepidoptera

    Author : Karin Näsvall; Niclas Backström; Simon Martin; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Chromosomal rearrangements; karyotype evolution; recombination rate; Lepidoptera; genome structure; molecular evolution; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : The evolutionary consequences of genome restructuring and chromosomal rearrangements can be significant, but the underlying mechanisms are poorly understood. This thesis explores the relationships between genome restructuring, recombination, and maintenance of genetic diversity in different butterfly species. READ MORE

  7. 15. Speciation genetics of recently diverged species

    Author : Venkat Talla; Niclas Backström; Nicola Nadeau; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Speciation; Leptidea; Lepidoptera; chiffchaff; Cryptic species; genome-scan; Diapause; Biology with specialization in Evolutionary Genetics; Biologi med inriktning mot evolutionär genetik;

    Abstract : Species differentiation can be a consequence of evolutionary forces including natural selection and random genetic drift. Patterns of genomic differentiation vary across the tree of life. This variation seems to be dependent on, for example, differences in genomic architecture and molecular mechanisms. READ MORE
